I am still seeing this issue using:
jai-imageio-core 1.3.1
jai-imageio-jpeg2000 1.3.0

[THausherr]

Because 1.3.0 is from 2015. If you want to test the change, then you'd have to build from the repository.

Thanks, that's what I planned on doing. I was thinking Jugen meant that the issue was fixed in a release.

THKausherr,
I have built my own jai-imageio-jpeg2000-1.3.1-SNAPSHOT.jar and added it to my project library but now I get this error like I don't have it:
Cannot read JPEG2000 image: Java Advanced Imaging (JAI) Image I/O Tools are not installed
any idea why this may be?

[THausherr]

You need to make sure that the new jar is part of your classpath, and also that the old jar isn't. And this must also be at runtime.

Maybe I am building the J2000 jar incorrectly.
I am building jai-imageio-jpeg2000-1.3.1-SNAPSHOT.jar by: Export>Java>Jar file
To my project I added libs folder
I added libs folder to Java Build Path>Source
I copied my jai-imageio-jpeg2000-1.3.1-SNAPSHOT.jar to the libs folder
I added external jar in Java Build Path>Libraries
I removed jai-imageio-jpeg2000 1.3.0 Maven dependency
I get the Cannot read JPEG2000 image: Java Advanced Imaging (JAI) Image I/O Tools are not installed error
I remove my jar and copy the original 1.3.0 jar to my libs folder and add that external jar...then it works but obviously with the black stain.

**I realize I shouldn't need to add the libs folder to source but have been trying everything to get this to work

EDIT: built jar using Run As>Maven Install and now it works. Using the maven reference now instead of adding external jar. Just wasn't thinking I guess. Thanks for the help, the black stains are now gone.

My built jai-imageio-jpeg2000-1.3.1-SNAPSHOT.jar has a size of 456KB.

Another trick to see whether the file is in your classpath would be to access a class from there, e.g. com.github.jaiimageio.jpeg2000.J2KImageReadParam .

Ink blot problem now fixed, thanks. But the second PR mentioned at the beginning of this issue ( faceless2@94e047e ) wasn't committed, that one prevents garbled images in rare cases.
